Abstract: Methods and systems are provided for a rebalancing reactor of a flow battery system. In one example, a pH of a battery electrolyte may be maintained by the rebalancing reactor by applying a negative potential to a catalyst bed of the rebalancing reactor. A performance of the rebalancing reactor may further be maintained by treating the catalyst bed with deionized water.

Abstract: In the disclosed method for the reshaping (adornment, repair, covering, prosthetic extension, etc.) of essentially rigid, keratinaceous surfaces such as nail plates with a free radical-polymerizable acrylic ester, the free radical initiator contains an encapsulated compound of the formula III wherein R1 through R4 are identical to or different from each other and are hydrogen, a mononuclear carbocyclic aromatic group, a C1-C18 aliphatic group, a C1-C18 aliphatic radical substituted with a mononuclear carbocyclic aromatic group, a cycloaliphatic group or an aromatic radical having from 6 to 10 ring carbon atoms and up to five aliphatic or oxy- or oxo-aliphatic substituents, with the proviso that at least R3 or R4 is hydrogen. The compound of formula III, in chemically-curable systems is encapsulated into the polymer matrix and utilized in combination with a metal salt co-catalyst that is mixed with the polymer and, optionally, an organic buffering compound and a crosslinker.
